PROBLEM TO BE SOLVED: To provide compounds which allow easy incorporation of radionuclides for single photon emission computed tomography (SPECT) and positron emission tomography (PET), and methods for imaging prostate cancer cells and angiogenesis that impart good contrast.SOLUTION: A compound includes as an imaging tracer a radioisotope substituent of the formula in the figure. (Y is NR' where R' is H or an alkyl group; Z is a carboxyl group, ester group or tetrazole group; Q is H or a protective group; and R is an alkanoyl group having as a substituent a specific group having a radioisotope substituent of F, I or the like.)SELECTED DRAWING: None |
